You leave it up to a FA to determine if it looks like "something to worry about"
Talking about technical issues of an airplane and not coffee spilled on someones pants I would say this is a bit too much trust. "I would assume they pass it on..." speaks the same language.
I have seen FAs (especially intercontinental) that cant even read the manifest without extra strong glasses. To investigate the wing from a distance and relying on their expertise is a little risky IMHO.
